Yes, I find making the inspector's job easy makes my job easy.
A question about the 2012 port size rule (R71):

...maximum 1/8 in. NPT port diameter...

What does that port size specification mean? The KOP supplied valve had M7 ports, not 1/8 NPT ports. Is a 1/8 NPT port bigger than an M7 port?
Would a valve with 1/4" push-to-connect ports be legal? (1/4" push-to-connect fittings work with the KOP-supplied 1/4" tubing.)
...or would we have to purchase valves with 1/8" NPT ports and then add 1/8" NPT to 1/4" push-to-connect fittings to be legal?
An installation would be a lot cleaner if the valves already had 1/4" push-to-connect ports since those interface directly with the required tubing.
All I have to say is ---
